The roots that come out of the netpot can stay under water 24/7. They are water roots. It's the rootball or air roots inside the netpot that needs the oxy time. Too much drip. We only drip every 2 hours for 15 minutes. It can go longer between drips.

There is no overwatering in hydro or soil. It is drowning. Think about it raining for 3 days. That's about the limit then the air roots need the oxy or they start to drown.

From your pic's I would cut back on drip and bring up the water level of your rez to about 2 or 3 inches below netpot.

I don't think the canoeing of the leaves like that are overwatered. You should fill out the trouble form and let us really help you find the problem.
LOC NAR on probation Reviewed by LOC NAR on probation on . wilting- too much water? ph? or nutrient? I am having a prob with plants wilting. I am running a drip system;330ppm, 6.0ph, 100w flourescent My light is set on 20/4 and my nutrients flow 15 on then off The only thing I can figure is that they are getting too much water because the roots just recently started really getting down into the solution. I have backed off the feeding to 15 on the 30 off for a couple hours to see if there is any improvement. Also my nute temp has recently risen to around 70. Any ideas? Rating: 5
